HampshireHog Posted November 23, 2020 Share Posted November 23, 2020 Hi all , is there a marked difference between the 200Tdi and 300Tdi heads & are they swappable or do you have to sacrifice a goat or some-such , any info greatly received .

Ex Member Posted November 23, 2020 Share Posted November 23, 2020 Injector size and position is different. Rocker assembly and valve cover is different. Thermostat housing connection is different. They can be interchanged if you do not mind adjusting things to accommodate the difference. Quote Link to comment Share on other sites More sharing options...
miketomcat Posted November 24, 2020 Share Posted November 24, 2020 I've heard they are a straight swap but you need 300tdi pistons as well. Not tried it myself but the guy I was talking to was adamant it was that simple. Mike Quote Link to comment Share on other sites More sharing options...

A Disco and Defender head are identical FYi in case a disco one is easier to find Quote Link to comment Share on other sites More sharing options...
HampshireHog Posted November 24, 2020 Author Share Posted November 24, 2020 Thanks fellas , so it’s doable but comes down to costs in reality , I’ve got a Discovery 200Tdi lump that I had intended to completely rebuild but have discovered hairline cracks between the seats of number two’s valves and with heads being expensive and getting harder to find a good one I wondered about the swap . Thank you all once again 👍 Quote Link to comment Share on other sites More sharing options...
